FRAME FOR SAUSAGE CASINGS.

Application filed March 26, 1928. Serial No. 264,946.

This invention relates to improvements in frames for stretching fabricsausage casings during the. coating operation.

The invention has to do primarily with a Wire frame or form which servesto hold the fabric casings in a stretched or extended condition in orderthat the coating material may be evenly and uniformly distributed uponthe fabric.

For the process of coating the fabric with a gelatinous mixture Whichhardens upon standing or after beng properly treated, as by smoking,reference is made to my co-pend ing application, Serial No. 237,991,filed December 5, 1927.

Fig. 1 is a perspective view of the frame with the casing shownstretched over the frame.

Fig. 2 is a side view of the frame.

Fig. 3 is a top view of the frame shown in Fig. 2.

Referring to the drawings, the form or frame consists of a plurality oflongitudinal. wires 1, these wires being preferably bent and connectedby spot welding or otherwise at points where the wires cross, thusassuring a rigid construction. At the top of the frame is an oval shapedWire member 2 which is also spot welded to the longitudinal wires, andacross the oval member is a spreader 3 into whichv is bent a hook orhanger 4. Along the top edge of the frame or at intervals on the ovalwire 2 are affixed pins or piercing 'members 5 over which the fabric isdrawn to prevent its displacement on the frame during the coatingoperation. rEhe fabric casing is designated as 6 in Fig. 1 of thedrawings.

It has been found that in coating the fabric casings it is essential tostretch the casing on a frame rather than a solid form as the fabric isporous and where a solid form is used the coating material readilypasses through the fabric and adheres to the form. This condition isundesirable as the coating material must be spread upon the outersurface of the fabric and prevented from saturating entirely through thefabric,

for to do so would affect the meat or sausage filling with which thecasings are filled.

It is, of course, obvious that differentsizes of frames will benecessary for different types of sausages. Listed below are in generalthe sizes used for common types of sausage casings:

4 X 28 export hog bung.

5 X 28 export sow bung. 6 x 24 No. 1 beef bung. 8 X 17 beef bladder.

9 x 18 large beef bladder.

The casings consist of an open-ended, elongated fabric container ofrelatively open or porous fabric. This container is slipped over the endofthe frame and is drawn onto the frame until it completely fills thefabric casing, the upper edges of the casing being pierced by theholding pins 5. These pins rigidly hold the fabric in position while thecoating material is spread over` the outer surface of the fabric, eitherby brushing or by dipping. The frames are then hung in a drying room bymeans of the hanger 4, and are smoked or otherwise treated to harden andfix the coating material on the fabric. The casings are then removedfrom the frames and filled with sausage meat.

The frame shown in the drawings is constructed of a bent wire and spotwelded. While this construction is preferred, it is appreciated that theforms may be constructed of material other than metal, and the spreadingelements of the forms fastened otherwise than by spot welding, withoutdeparting from the scope or spirit of the invention.

I claim asI my invention:

1. A frame for coating sausage casings, comprising longitudinalspreaders for extending the casing during the coating operation, andmeans along the upper edge of the frame for holding the casing againstdisplacement on the frame.

2. A frame for spreading fabric sausage casings during the coatingoperation, comprising bent and connected wire members shaped into a formto fit Within the casing and hold the fabric in a stretched condition,and means l'or holding the fabric casing against displacement on theframe.

3. A. frame for stretchingr sausage easings during the coatingoperation, comprising a skeleton frame adapted to lit into the casing tohold the same in extended, stretched eondition, ointed members on theupper edge of the flrarne for holding the casing against displacement,and hanging means for supporting the frame during the drying or smokingperiod.
